The design was produced using SolidWorks 2010. The larger cylinder was created as an extruded boss with the initially provided dimensions. After this the smaller cylinder was created using an extruded boss with the provided dimensions. The connecting section was created using an extruded boss as well with the dimensions provided…
After the model was imported to ALGOR FEA the log was checked to ensure that there were no import errors or missing geometry. Then a fixed boundary condition was applied to the internal surface of the larger cylinder after which a normal force of 500 N was applied to the internal surface of the smaller cylinder. The application of a fixed boundary condition to one area of the model meant that the model was constrained from moving within that axis of rotation or translation. The model could either rotate on the longitudinal axis of the constrained cylinder or it could translate in either three directions (x, y and z). Implementing a fixed boundary condition indicates that the model is unable to move in any direction at all. Generally a fixed boundary condition can be considered analogous to a welded piece that is unable to move but can bend or flex under applied force. Though this may not simulate the actual conditions one on one (where the crank actually rotates though it does not translate at all), but it does provide a satisfactory numerical investigation model. Furthermore the application of a normal force to the other cylinder’s internal surface indicates the application of normal average force when the crank will be in use. ...
